Functions

func SetTunnelMap

func SetTunnelMap(m *Map)

SetTunnelMap sets the tunnel map. Only used for testing.

Types

type Map

type Map struct {
	*bpf.Map
}

Map implements tunnel connectivity configuration in the BPF datapath.

func NewTunnelMap

func NewTunnelMap(mapName string) *Map

NewTunnelMap returns a new tunnel map.

func TunnelMap

func TunnelMap() *Map

func (*Map) DeleteTunnelEndpoint

func (m *Map) DeleteTunnelEndpoint(prefix cmtypes.AddrCluster) error

DeleteTunnelEndpoint removes a prefix => tunnel-endpoint mapping

func (*Map) GetTunnelEndpoint

func (m *Map) GetTunnelEndpoint(prefix cmtypes.AddrCluster) (net.IP, error)

GetTunnelEndpoint retrieves a prefix => tunnel-endpoint mapping

func (*Map) SetTunnelEndpoint

func (m *Map) SetTunnelEndpoint(encryptKey uint8, prefix cmtypes.AddrCluster, endpoint net.IP) error

SetTunnelEndpoint adds/replaces a prefix => tunnel-endpoint mapping

func (*Map) SilentDeleteTunnelEndpoint

func (m *Map) SilentDeleteTunnelEndpoint(prefix cmtypes.AddrCluster) error

SilentDeleteTunnelEndpoint removes a prefix => tunnel-endpoint mapping. If the prefix is not found no error is returned.

type TunnelIP

type TunnelIP struct {
	// represents both IPv6 and IPv4 (in the lowest four bytes)
	IP     types.IPv6 `align:"$union0"`
	Family uint8      `align:"family"`
}

+k8s:deepcopy-gen=true

type TunnelKey

type TunnelKey struct {
	TunnelIP
	ClusterID uint8  `align:"cluster_id"`
	Pad       uint16 `align:"pad"`
}

func (*TunnelKey) New

func (k *TunnelKey) New() bpf.MapKey

func (TunnelKey) String

func (k TunnelKey) String() string

String provides a string representation of the TunnelKey.

type TunnelValue

type TunnelValue struct {
	TunnelIP
	Key uint8  `align:"key"`
	Pad uint16 `align:"pad"`
}

func (*TunnelValue) New

func (k *TunnelValue) New() bpf.MapValue

func (TunnelValue) String

func (k TunnelValue) String() string

String provides a string representation of the TunnelValue.
